Glycine* 2-aminoethanoic acid) is an optically inactive amino acid. Which of the following compounds is formed NOT because of the acid-base property of glycine?
|
|
H2NCH2COONa
|
|
|
CH3OOCCH2NH2
|
|
|
HOOCCH2NH3Cl
|
|
|
HOOCCH2NHOOCCH3

Explanation:
Detailed explanation-1: -Glycine is the simplest amino acid. It is different from all the other amino acids because it is the only amino acid which do not have asymmetrical carbon atom. Hence, glycine is optically inactive.
Detailed explanation-2: -Glycine has no chiral center. So, it is optically inactive.
Detailed explanation-3: -Glycine is the only amino acid that is not optically active because it does not have a carbon chiral center. In order for a carbon to to be a chiral center, it must have 4 different R-groups attached to it.
Detailed explanation-4: -Complete answer: The absence of asymmetric carbon atoms makes glycine optically inactive that means glycine does not rotate the plane polarised light.
